Product Description
EpoxAmite™ 102
EpoxAmite™ 102 is an easy-to-use liquid epoxy system formulated for a wide variety of fabrication applications. EpoxAmite™ 102 includes the EpoxAmite™ 100 Base and the EpoxAmite™ 102 MEDIUM Hardener. EpoxAmite™ 102 is unfilled, low in viscosity, odorless and cures at room temperature. Cured epoxy displays exceptional physical and performance properties. It can be sanded, shaped, machined, drilled, tapped and painted.
EpoxAmite™ 102 can be used with reinforcements such as S-Glass, E-Glass, Kevlar and Carbon fibers for lay-up applications or composite parts. EpoxAmite™ 102 can also be mixed with fillers such as fumed silica for gel coat applications. Urefil™ 3, Urefil™ 7 and other fillers can be added for fairing, filleting or bonding applications.
Applications: Wet Lay-Up Lamination, General Bonding & Repair, Clear Coating - Gel Coating, Barrier Coating, Thin-Section Casting, Water Proofing, Patching & Small Laminates
Also available: EpoxAmite™ 101 FAST SET and EpoxAmite™ 103 SLOW SET
Smooth-Cast™ 321
The Smooth-Cast™ 320 Series consists of ultra-low viscosity casting resins that yield virtually bubble-free off-white castings. The Smooth-Cast™ 320 resins are sister products to our popular Smooth-Cast™ 300 Series of bright white plastics, but are easier to color using SO-Strong™ or Ignite™ color tints. Smooth-Cast™ 320 series is easy to mix and pour, offering the convenience of a 1A:1B by volume or 100A : 90B by weight mix ratio.
The Smooth-Cast™ 320 Series resins readily accept pigments and fillers (such as URE-FIL™ 3, 5 and 7 from Smooth-On). Fully cured castings are tough, durable, machinable and paintable. They resist moisture and mild solvents. Applications for Smooth-Cast™ 320 Series resins include reproducing small to medium size sculptures, making prototype models, special effect props, decorative jewelry and taxidermy (bones, antlers, teeth etc.).
